ZeroGPT

ZeroGPT is an online tool designed to detect whether a given text has been generated by artificial intelligence models, including ChatGPT, GPT-5, Gemini, Grok, DeepSeek, and other large language models. The service allows users to input text directly into a text box, with a limit of 15,000 characters per free check, and supports file uploads for bulk or longer content analysis. After submission, the tool processes the text and returns a detailed report that highlights each sentence suspected of being AI-generated, along with a percentage gauge indicating the overall proportion of AI-written content within the document. This per-sentence highlighting is a core feature, enabling users to see exactly which parts of the text may have been produced by an AI, rather than just a single aggregate score. The detector is optimized for high accuracy across multiple AI models, including newer versions like GPT-5, and is regularly updated to keep pace with evolving generation techniques. Users can paste content from essays, articles, emails, social media posts, or academic papers. The tool is also available for integration into other platforms via API, though the primary interface is web-based. In addition to the core detection function, ZeroGPT offers a suite of supplementary tools accessible from the main dashboard: an AI Image Detector to identify AI-generated images, a Background Remover for photos, a Paraphrasing Tool to rewrite text while preserving meaning, a Grammar Checker for surface-level corrections, a Plagiarism Checker that compares text against a vast database of sources, and a Summarizer that condenses long documents into key points. Each of these tools operates as a separate module but shares the same account system, allowing users to switch between them without re-
